Basic Operation
6.3.2 V/f Pattern Selection: E1-03
6 - 24
J
Setting a User-defined V/f Pattern: E1-03 = “F”
D
Constants E1-04 through E1-10 can be set by the user when E1-03 has been set to “F.” These constants
are read-only when E1-03 isn’t set to “F.”
D
When making the V/f characteristics a straight line, set the same value in E1-07 (middle output frequen-
cy) and E1-09 (minimum output frequency). In this case, constant E1-08 (middle output frequency volt-
age) will be disregarded.
D
The user constant numbers for motor 2 are given in parentheses.

* 1. These values are for 400-VClass Inverters; multiply the values by approx. 1.5 for 575-VClass
Inverters.
* 2. The factory setting depends on the Inverter capacity. The factory settings shown in the table
are for 400-V Class, 200 to 800 kW Inverters. (See page 8 - 41.)
Refer to the graphs for “Setting: 1” on page 6 - 23.
* 3. If E1-13 is set to 0.0, E1-13 will be set to the same value as E1-05 following autotuning and
does not need to be set.
D
The factory settings for E1-07 through E1-10 will be set according to the control method whenever the
control method is changed. The factory settings shown in the table are for V/f control. See page 8 - 41.)

The four frequency settings must satisfy the following formula:
E1-04 (F
